Hi everyone, I want to convert an R function into VBA for calculating the eigenvectors and eigenvalues of a matrix using the "Power Method". The function is: PowerMethod <- function(x, tolerance) {     my.mat <- var(x[,-1], na.method="available")     matSize <- dim(my.mat)[1]     eigenVec <- matrix(NA, nrow=matSize, ncol=matSize)     eigenVal <- rep(NA,

I want to make a multi-dimensional array. To be specific I want to make the following array results<-array(0,dim=c(2,2,64,7)) This is the code I have created but it gives no result due to the error "subscript out of bound". x<-rep(7,7) # Missingness in intervention y<-rep(7,7) # Missingness in control

Dear R users, I am using the beadarray package. I am trying to upload raw bead-level data using these commands: ######################################################## library(beadarray) datadir <- ("C:/Computer_programs/R/beadarray/cecilia") targets = read.table("targets.txt", sep = "\t", header = TRUE, as.is = TRUE) BLData = readIllumina(arrayNames =NULL,

When I mistakenly use file.copy() with a directory for the 'from' argument and a non-directory for the 'to' and overwrite=TRUE, file.copy returns FALSE, meaning it could not do the copying. However, it also replaces the 'to' file with a zero-length file. dir.create( fromDir <- tempfile() ) cat(file = toFile <- tempfile(), "existing file\n")

Hi List! Is there a way to iterate through an associative array when prototype.js is used? arrayname.each(function (i) { alert(i); }); seems to work only for numeric arrays.

I was running some sample code from a help page tonight and wished to redirect the sample output to my Desktop under Linux (Mint-Debian 64 if it makes a different). I was surprised to find that file name expansion using the ubuquitious "~/" was not recognized, in fact it caused R to crash. Is this expected behavior? See my output below and sessionInfo(). Also, not shown, but

From: Hung-chi Lihn <hlihn at google.com> The current Lua.c32 does not enable io.read() due to some missing library functions. However, this strongly limits the Lua script from getting user inputs and reading files (even in pxelinux via TFTP). This patch enables io.read() in Lua.c32 with some restrictions: 1. the io.read("*line") is fully supported. 2. the

Under Solaris 10 on a 4 core Sun Ultra 40 with 20GB RAM, I am setting up a Sun StorageTek 2540 with 12 300GB 15K RPM SAS drives and connected via load-shared 4Gbit FC links. This week I have tried many different configurations, using firmware managed RAID, ZFS managed RAID, and with the controller cache enabled or disabled. My objective is to obtain the best single-file write performance.

The Rgraphviz package index says nothing about reading "dot" files. (it has "toFile" to write them but no fromFile). How do I create an Ragraph object? (either by reading a dot file or from a list of edges with weights and vertices with names and other attributes). -- Sam Steingold (http://sds.podval.org/) on Ubuntu 12.04 (precise) X 11.0.11103000 http://www.childpsy.net/

We had been using R1.2.3 "print tip lowess function" as described by Terry Speed's group to normalize microarray data and up until this week the commands we were using were working fine. First, we load our data using arrayname<-read.table("filename", header=T) and then check that the table is OK. We format the data list using setup1<-init.data() and usually get a

Hello: I modified benchmark used in http://www.informatik.uni-frankfurt.de/~stst/benchspl.txt now the attached code will work with R, except for last test for some reason (Sorry ran out of time to play with this). Immediate problem is that R does not show fraction of seconds. So, that kinda makes comparison some what hard. I also looked at memory and CPU usage on NT console. R seems to go

Hi again everyone, I''ve 2 tiny doc patches mostly involving grammar fixes (and errant whitespace elimination). My English is not perfect so any review would be very welcome.

Hi r-users, I would like to draw line plots. However, the plot starts from 11121 data and plot data ENTRY last in the plot. Here is the code and data. datn <- read.table(header=TRUE, text=' LEVEL STATUS CGPA DIPLOMA ENTRY 3.32 DIPLOMA 11121 2.91 DIPLOMA 11122 2.90 DIPLOMA 12131 2.89 DIPLOMA 12132 2.89 DIPLOMA 13141 2.93 DIPLOMA 13142 2.96 DIPLOMA 14151 2.76 DIPLOMA 14152 2.73 STPM

Hi, Thanks for the reproducible example. Looking at str(datn) would give you a clue. STATUS is a factor because it contains character values. Factor levels by default are alphabetical with numbers first, but you can change those. > str(datn) 'data.frame': 36 obs. of 3 variables: $ LEVEL : Factor w/ 4 levels "DIPLOMA","MATRIC",..: 1 1 1 1 1 1 1 1 1 4 ... $

Greetings- I'm about to embark on a new installation of Centos 6 x64 on 4x SATA HDDs. The plan is to use RAID-10 as a nice combo between data security (RAID1) and speed (RAID0). However, I'm finding either a lack of raw information on the topic, or I'm having a mental issue preventing the osmosis of the implementation into my brain. Option #1: My understanding of RAID10 using 4

Hi all, Probably a rudimentary question. I have a flat file that looks like this (the real one has ~10e6 elements): 10110100101001011101011 and I want to pull that into R as a vector, but with each digit being it's own element. There are no separators between the digits. How can I accomplish this? Thanks in advance! Matt -- Matthew C Keller Asst. Professor of Psychology University of

Hey I got a question regarding sortables. I can drag and drop the items on a page to different locations. But when I refresh the page the contraols are goin to their inital positions. Is there any way that I can make them stay in their new positions even after post back (refresh)??? Thank you. On 11/11/05, rails-spinoffs-request@lists.rubyonrails.org <

Prototype.js seems to extend the standard javascript array constructor. It adds some methods and properties. If I do the for (key in array) I get additional keys that I didn’t add. ________________________________ Von: rails-spinoffs-bounces@lists.rubyonrails.org [mailto:rails-spinoffs-bounces@lists.rubyonrails.org] Im Auftrag von Gregory Hill Gesendet: Freitag, 11.
